[alsa-devel] [PATCH v2 1/8] ASoC: Intel: add function to load firmware image
From: "Lu, Han" han.lu@intel.com
Add a general method to load firmware image, and apply to base firmware image loading. With the method, the driver will support loading multiple different modules in order to support different features.

I'm not clear how this setting is saved when the module is not in RAM on the DSP. If the module enable/disable calls do that that's fine but I'd expect the function to return an error if the module isn't loaded (or better yet for the control not to be made visible to userspace at all) - we shouldn't be silently ignoring what the user is setting.

[Han] if module is not in RAM on the DSP, sst_hsw_is_module_loaded() will return false. Also sst_hsw_module_enable() and sst_hsw_module_disable() will check the module status in DSP before send IPC commands to DSP. In case sst_hsw_is_module_loaded() return false, (eg. System go RTD3 and modules in DSP RAM be unloaded) the user setting will be stored in variant u32 enabled_modules_rtd3, which is implemented in patch 0005. So which is better for next version of patch, to add error return here, merge patch 0005 with 0004, or do not change this part? Thanks.

It's better to merge the two patches so that it's clear that everything is working fine - in general the idea is that things should work after every patch and people shouldn't be finding problems in the patch series which are fixed later on in the same series.

There are 2 issues on waves firmware: 1. the parameters read from DSP do not match parameters set to DSP. 2. the parameters in DSP will lost on RTD3. The patch add a buffer array to store parameter lines, so parameters can be read back from buffer, and be relaunched to DSP when resume from RTD3. The size of buffer is 160 parameter lines. Also add kcontrol command to reset the buffer: cset "name='Waves Set Param' 0xff"

Add a general method to load firmware image, and apply to base firmware image loading. With the method, the driver will support loading multiple different modules in order to support different features.
This doesn't apply against current code - you should be sending things against my git tree (or -next is often close enough).

[Han] sorry, I made patches against for-next branch, and I just run $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git $ cd sound $ git checkout origin/for-next -b for-next And apply the patches manually $ patch -p1 < 0001-ASoC-Intel-add-function-to-load-firmware-image.patch $ patch -p1 < 0002-ASoC-Intel-add-function-to-load-sound-effect-module-.patch ... $ patch -p1 < 0008-ASoC-Intel-enable-parameter-restore-for-sound-effect.patch But didn't find conflict. Is there any mistake in my operation, or could you please share the error log so I can correct my patch? Very sorry for inconvenient.

I've managed to find the dependencies and resolved this, applied patches 1-3.
